5 JAMA 2016;; 315 (8) 801 The current use of 2 or more SIRS criteria to identify sepsis was unanimously considered by the task force to be unhelpful. Changes in the white blood cell count, temperature, and heart rate reflect inflammation, the host response to danger in the form of infection or other insults. The SIRS criteria do not necessarily indicate a dysregulated, life-threatening response. The Original Sepsis Paradigm It is our response... that makes the disease Lewis Thomas, NEJM,

6 The problem has not been the therapies tested, but the underlying hypothesis that massive, uncontrolled inflammation is the dominant cause of sepsis. - Roger Bone, JAMA 1996 Sepsis, A Tale of 2 States Systemic Inflammatory Response Syndrome (SIRS) Compensatory Anti-inflammatory Response Syndrome (CARS) Leukocyte Activation Sepsis-Induced Tissue Injury Leukocyte Deactivation Sepsis-Induced Immunosuppression Systemic Inflammatory Response Syndrome (SIRS) Compensatory Anti-Inflammatory Response Syndrome (CARS) Cytokine/mediator Levels TNF, IL-1b Chemokines IL-6 Leukotrienes Anti-inflammatory cytokines (e.g. IL-10, IL-1ra) Prostaglandins Inhibitors of TLRs Time Post Insult

Critical Care Medicine. 41(9): , Infiltration of Pressor Agents Treatment 1. If the pt is relying on the agent for hemodynamics, switch the pressor to another IV or place an immediate IO or central line. 2. Do not pull the cannula yet! 3. Withdraw as much fluid from the cannula as you can 4. Administer subcutaneous phentolamine mesylate using 25 G or smaller needle Inject 0.1 to 0.2 mg/kg (up to a maximum of 10 mg) through the catheter and subcutaneously around the site. Comes in 5 mg per 1 ml vials. Place in 9 ml of NS Administer as soon as the extravasation is detected, even if the area initially looks just a little white or OK. Should see near immediate effects; otherwise consider additional dose May cause systemic hypotension 5. Now pull the catheter! 6. Consult Plastics
